Fifty-one-year old Sarah Mupakati does not remember the last time she ate sadza, a cooked cornmeal. She opens her one-room tent which she shares with her five grown-up children - the corner that serves as her pantry is empty. It has been like that for the past month. The little she has been getting from barter trading is used up that same day. It is all too easy to understand her relief as she joins the queue to receive her first food rations from the World Food Program (WFP).
